hibernate 初級問題

package com.gktrim.Hibernate;
import org.hibernate.cfg.*;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.apache.commons.logging.*;
import org.hibernate.cfg.Environment;
/**
* @author Administrator
*
*/
public class InsertMachineSpeed {


/**
* @param args
*/
public static void main(String[] args) {
// TODO 自動產生方法 Stub

Configuration cf=null;
SessionFactory sf=null;
Session se=null;
cf=new Configuration().configure("");

}
}
提示出錯：
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

這是哪裡出問題？

警告，不用管也可以。
是你的log4j配置有问题。

無法寫入數據庫啊，全部錯誤為：
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
org.hibernate.HibernateException: Dialect class not found:
at org.hibernate.dialect.DialectFactory.buildDialect(DialectFactory.java:81)

全部代碼為：
package com.gktrim.Hibernate;
import org.hibernate.cfg.*;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.apache.commons.logging.*;
import org.hibernate.cfg.Environment;
/**
* @author Administrator
*
*/
public class InsertMachineSpeed {


/**
* @param args
*/
public static void main(String[] args) {
// TODO 自動產生方法 Stub



//p.setAotoid("1");

try{
SessionFactory sf = new Configuration().configure().buildSessionFactory();
Session session = sf.openSession();
Transaction tx = session.beginTransaction();

SgMachineSpeedId p = new SgMachineSpeedId();
p.setSeiralNo("zhang");
p.setMachineType("hello");

System.out.println("成功");
session.save(p);
tx.commit();
session.close();
System.out.println("成功2");
}catch(Exception ex){
ex.printStackTrace();

System.out.println("失敗");
}

}

}

org.hibernate.HibernateException: Dialect class not found:

应该不是数据库驱动没有吧，是不是你的Dialect 写错了，配置文件中的？

[cyxxde]

下面是配件文件的內容，應該沒錯吧？

<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
就这句不对 dialect类找不到 看一下异常
修改为
org.hibernate.dialect.FirebirdDialect
